Acid Phosphatase Localization in Rabbit Eosinophils
Eosinophil (and heterophil) leukocytes of glycogen-induced rabbit peritoneal exudates were fixed for 1(1/2) min in 2% glutaraldehyde and examined for acid phosphatase activity both biochemically and cytochemically. Biochemical assays showed that enzymatic activity had been inhibited by only approximately 10% under these conditions. The cytochemical reaction in the eosinophil was confined to the...
متن کاملIntracellular Localization of Acid Phosphatase
The acid phosphatase activity of rat liver homogenates and of nuclear and cytoplasmic fractions isolated therefrom (by differential centrifugation) was determined biochemically in a series of experiments. For each liver, Gomori's histochemical test for acid phosphatase was run in parallel. No correlation was found between the biochemical and the histochemical results. According to the former, t...
متن کاملCytochemical Localization of Acid Phosphatase Activity in Granule Fractions from Rabbit Polymorphonuclear Leukocytes
When rabbit peritoneal exudates (97% polymorphonuclear [PMN] leukocytes, 2% mononuclear cells) were fractionated by zonal sedimentation or isopycnic centrifugation, four fractions (A, B, C, and D) were obtained, as reported earlier. "A" consisted largely of PMN azurophil granules, "B" of PMN specific granules, and "D" of membranous elements. The source of the more heterogeneous "C" fraction (co...
متن کاملUltrastructural Localization of Dialyzed Iron-reactive Mucosubstance in Rabbit Heterophils, Basophils, and Eosinophils
For ultrastructural localization of acid mucosubstances in rabbit granulocytes, bone marrow and buffy coat specimens were fixed with formalin, glutaraldehyde, or osmium tetroxide, sectioned at 40 micro, and stained with the Rinehart and Abul-Haj solution of dialyzed iron (DI). Heterophils revealed DI staining on the outer surface of the plasma membrane, in the Golgi complex involved in primary ...
متن کاملLocalization of Phosphatidic Acid Phosphatase Activity in Granular Pneumonocytes
The alveoli of the mammalian lung are lined by a film of surface-active material (surfactant) which is commonly believed to be a phospholipid (1, 5, 8, 11) . A considerable body of evidence has accumulated which suggests that surfactant is synthesized by the granular pneumonocytes (type II cells) of the alveolar epithelium (1, 9, 10) . Although a number of acid hydrolases have been demonstrated...
